How to make this make no craters in the terrain?

Here's the scripts to the pellets.

wait(3) --Code 1
                g = Instance.new("Explosion") 
                g.Parent = game.Workspace 
                g.Position = script.Parent.Position 
                g.BlastRadius = 5
                g.BlastPressure = 100000    


script.Parent:remove()

--Code 2

pellet = script.Parent


function onTouched(hit)
    humanoid = hit.Parent:findFirstChild("Humanoid")
    if humanoid~=nil then
        g = Instance.new("Explosion") 
                g.Parent = game.Workspace 
                g.Position = script.Parent.Position 
                g.BlastRadius = 5
                g.BlastPressure = 1000
                pellet:remove()
           else
                script.Parent.PelletScript2.Disabled = false
                script.Parent.PelletScript:remove() 
    end
end



connection = pellet.Touched:connect(onTouched)
